Topic created on: February 28, 2010 01:08 CST by LOPAN .

I'm debuggin a fullscreen DirectX game (Tropico 3; there is no option to run in windowed mode), but when a breakpoint is hit, the game simply freezes and doesn't return properly to IDA PRO debugger. The keyboard doesn't work and I have to press ctrl+alt+del to go back to my desktop, and after then it is the mouse that doesn't work and the mouse pointer in the desktop is still the icon from the game itself. It's bad debugging just with the keyboard and the desktop all messed up.

Is there something I can do for a DX application to return properly to the debugger when a breakpoint is hit?

You could try remote debugging. Run win32_remote.exe and the game on one machine/VM, the debugger's GUI on the other.

Dennis' suggestion is more clean but you could also use some tools to force the windowed mode (DxWnd)...

For the record: http://www.woodmann.com/forum/showthread.php?t=13453

TheColonial tutorials to solve Silver's DirectX crackme tells you how to patch the application to change from Fullscreen to Windowed (a boolean to fix, and the refresh rate to set at 0 value).
